It's not superfluous at all. Many of the folks posting here are at least incidentally harming a child, and see it as excusable because of misconduct of the child's mother.
I think the proper approach would be to go after the real father...why should the mother protect the true father...the courts should order her to name the sperm donor, and have it confimed with DNA.....that is if she can identified him....
Sorry I don’t think you can prove that “folks posting here are at least incidentally harming a child” because they don’t support a program where the fatherless pay for other’s children.
Although that seems to be the consensus, you keep arguing to convince others the state should impose the opposite. I think you are speaking to the wrong audience. This is not a socialist website.
